報告內容：
Metal ions play crucial roles in life processes either as an essential elements or therapeutical/diagnostic agents. It is crucial to identify metal-protein interactions at a proteome-wide scale which are difficult due to certain weak and transient interactions. We developed an integrated approach consisting of gel electrophoresis and inductively coupled plasma mass spectrometry, immobilized metal affinity chromatography (IMAC), fluorescence and bioinformatics to identify metal-associated proteins using bismuth antiulcer drug as an example. We have identified metal-associated proteins as well as to quantify the metals for fast metallome/proteome-wide profiling of metal-binding proteins. The multi-targets of bismuth(III) provide a rational basis in understanding the high efficacy and low antibiotic resistance of this class of bismuth drugs. We also show that an integrative metallomic approach represents a powerful tool for metals in biology and medicine as well as pharmacology of metallodrugs.
